To all whom z'tmoy concern:

Be it'known that I, GEORGE G. FLoYn, a citizen or the. United States,residing at Granite City, in the county of Madison and.

State of Illinois, have invented certain new and useful Improvements inCar-Trucks, of which the following is a specification.

This invention relates to im roved and novel means in, railway cantruc:constructions which will permit the ready and easy removal of thebolster lengthwise through its aperture of the sideframe. litany andvarious schemes have been provided for reaching this desired result, butI believe that the present invention provides a construction possessingseveral features and characteristics of novelty and improvement. Inacbolster; or, if desired, these columns may be wholly taken out of theside-frames. In

one embodiment of the invention the sides of the side-frame borderingthe bolster aperture are provided with vertical under-cut grooves toaccommodate correspondinglyforn'id columns, such grooves or recessesextending upwardly through the top of the side-frame to permit insertionof the columns, the latter resting on the lower ends of the grooves orrecesses so as to be supported thereby.

From a consideration of the detailed description of a preferredembodiment of the invention set forth below, which should be read inconnection with the accompanying drawing forming a part of thisspecification, it will be apparent that a car-truck including thisinventionis simple in construction, economical to manufacture, andrenders possible the desired results stated above.

In this drawingFigure 1 is a side elevation of a car-truck with partsomitted and the side-frame shown partially in section; Fig. 2 is apartial plan and partial horizontal section on line 2-2 of Fig. 1; Fig.3 is a central vertical cross-section through the side-frame with thecolumns omitted; and Fig. 4: is a perspective view of one of theremovable or shiftable columns.

By reference to the drawing it will be noted that the bolster 10 has onopposite Specification of Letters Patent.

faces of its end portion the spaced column guides 11, 11 providingbetween them grooves-or recesses 12 to accommodate the columns. Theside-frame 13 has the usual central opening 14 for the reception of thespring-plank 15, springs 16, and the end of the bolster. In the presentinstance this opening or aperture is of substantially rectangular form,being bounded by the opposite side walls 17 and 18, which at their lowerends are composed of transverse flanges, their upper ends .or portionsbeing considerably thickened as at .19 and supplied on their adjacentfaces with vertical centrally-disposed undercut grooves 20 terminatingat the top of the lower flange portions of such walls at 21, whereby toprovide seats or supports for the vertical removable or shiftablecolumns or bolster guides 22 in cross-section of substantially "it-form,whereby their lateral disengagement from such grooves is prevented. Theportions of such columns or guides protruding into the bolster aperture14 of the side-frame, as will be readily understood, form the columns orguides for the bolster and are intended to fit in the above-mentionedgrooves or recesses 12 of such bolster. The recesses 20 EX- tendupwardly through the top compression member 23 of the side-frame, thelatter completely encircling the top ends of such removable or shiftablecolumns or guides because of the bosses or enlargements 24: formed onthe lower part of such compression member. In order to prevent upwardshifting or displacement of such columns or guides each is provided orsupplied with a hole 25 extended therethrough near its upper end andadapted to receive'a pin 26 pass- -1ng thropgh holes 27 of theside-frame registering with the aperture 25. Such pins are, of course,readily and easily removable to permit the taking out or upwardwithdrawal of such disengageable columnsor guides. As is indicated, theaperture lei.- of the sideframe would be ordinarily constructed ofsubstantially the same width as the over-all transverse dimension of thebolster over its column guides 11.

The removal or withdrawal of the bolster is effected in substantiallythe following manner: The spring lti having been taken out, the bolstermay be either permitted to descend or may be maintained in the normalposition shown in Fig. 1. In any case, the

shii'table columns 22, after the pins 26 have I the bolster, the partsof the side-frame con- 90 been removed, are pushed upwardly, orstituting the side-walls of said aperture bewholly removed from theside-frame if deing grooved, and columns with which the sired, so as nolonger to reside in the guiding bolster column guides are adapted tocogrooves 12 of the bolster, and in such posioperate shiftably mountedin said grooves, tion of the parts the bolster is free to be there beinga projection and recess connec- .1 withdrawn longitudinally laterally ofthe tion between each column and one of the truck through the opening 14of the sidewalls of the groove, whereby when said colframe, as iscustomary in other construct-ions umns are moved out of normal positionthe of this general character. bolster may be taken out lengthwisethrough The manner in which a bolster would be the side-frame aperture,substantially as de- 40 placed in the truck and the columns broughtscribed. to proper position is obvious from the above 2.
